Preimplantation Genetic Screening (PGS)

Preimplantation Genetic Screening (PGS) uses next-generation sequencing, the most cutting edge technology available today, to screen embryos for aneuploidy, providing the most accurate results.

The growth of an embryo into a baby is guided by its chromosomes. When the embryo is missing or has extra chromosomes, the condition is known as aneuploidy. An aneuploid embryo is an embryo that is missing or has extra chromosomes.

PGS is aimed at helping patients make informed decisions, and improving their odds of IVF success.

Successful pregnancies begin with viable embryos

Aneuploid embryos are not usually viable. These embryos often fail to implant, and those that do, generally result in miscarriage. For aneuploid embryos live births, the most common genetic abnormality is Down Syndrome.

Fortunately, PGS can accurately identify those embryos so only viable embryos are selected for implantation. PGS improves IVF success rates and also reduces high-risk multiple births by enabling transfer of a single embryo.

PGS can eliminate effect of maternal age on implantation. And, can reduce negative effect of maternal age on miscarriage.

Aneuploidy exists across women of all age groups and increases with the woman’s age. Women over age 35 have almost double the risk of aneuploidy in comparison to younger women. When PGS is used to select embryos with the normal number of chromosomes, the negative effect of maternal age on implantation is eliminated, and, much lower miscarriage rates can be achieved.
